Bug#720345: 'apt-get update' considers connection failures non-transient
Package: apt
Version: 0.8.16~exp12ubuntu10.7
If a mirror fails in such a way as to trigger the "Unable to connect" error, it is not represented as a transient error.
To reproduce, add an unallocated IP to sources.list, e.g.,
deb http://10.26.57.199/repos/apt/foo precise dependencies main
for a repo that contains
then run apt-get update:
Ign http://10.26.57.199 precise InRelease

E: Some index files failed to download. They have been ignored, or old ones used instead.
[root@talos-linux64-ix-044.test.releng.scl3.mozilla.com ~]# echo $?
100
Expected result:
Exit status 0, since this is a transient failure of the host containing that repo.
http://anonscm.debian.org/loggerhead/apt/apt/debian-squeeze/view/head:/apt-pkg/algorithms.cc#L1495
should write "Some index files failed to download, they have been ignored, or old ones used instead." as a warning in that case.
Use case:
I have multiple mirrors of the debian repos used internally. Temporary failure of a single mirror should not cause 'apt-get update' to fail: that's why I have multiple mirrors!
